The following slides contain 1H and 13C-NMR spectra as well as GC/MS spectra for compound 2 shown below. After analyzing the spectra, assign all proton and carbon NMR signals using the numbering given on the structure. Additionally, present your data in table form including chemical shift, integration, coupling pattern, and coupling constants (where possible). For mass spectral data, justify key fragmentations (those which are starred*) by proposing fragment structures. 5 96337 03828 047734 739073 23444 14703 3 8 9 2...
